We are seeing improvements and emails are being delivered.

We will keep monitoring the situation closely.

We are still actively remediating the issue and have changed our mitigation. You might see deferrals in your webhooks or UI instead of delayed processing. Please note emails are still being retried.

To make sure emails will be delivered, we have increased our maximum wait time to 24 hours instead of 12 hours and are actively monitoring the situation in case further extension is needed. We hope to hear back from Microsoft's Sender Support as soon as possible.

This issue does not impact Microsoft 365 (Outlook 365) addresses nor other providers.

Broadcast is also not affected by the issue.

Our sincere apologies for the inconvenience.
